From the Northern Brewer web site - "Stan Hieronymus (author of Brew Like a Monk) and Kristen England (BJCP Continuing Education Director) bring you this very special kit. "Brouwerij'ed" on the left side of the Belgian town Malle solely for consumption by the reverent Cistercian brothers. This ale is not served or sold to the public, making it one of the rarest beers in the world. Made only from pilsner malt, hops, and yeast, the complexity that results from these simple ingredients is staggering: perfumey floral hops, ripe pear fruit, sour apple, spicy cloves, candied citrus and a slight biscuit character on the drying finish ... a monks' session beer."
